So this is definitely a basic question, but for some reason is getting past me....How do you tune the NAV OBS and ADF in the 747? I can easily adjust the frequency to whatever VOR station I choose, but for some reason I can't figure out where the adjustment dial is for the NAV OBS or the ADF.Please help....Tod

I'm away from my simming computer.. but I think I can help.The OBS (course), can be changed by placing the mouse-pointer over the course indication number (upper-right corner of the HSI). Not realistic, but it works.I don't think the 747 has an ADF gauge.. It has an RMI where one of the needles can be an ADF indicator.. and the compass "card" is slaved to the compass, so there's no adjusting it.
